docs: update role templates with hook-first startup protocol (gt-h6eq.9)

Updated all role prompt templates to document the startup hook protocol:
- polecat.md.tmpl: Added gt mol status check, self-pin from mail protocol
- witness.md.tmpl: Added gt mol status check, self-pin from mail protocol
- refinery.md.tmpl: Added gt mol status check, self-pin from mail protocol
- crew.md.tmpl: Added new Startup Protocol section with hook-first flow
- deacon.md.tmpl: Added gt mol status check, self-pin from mail protocol
- mayor.md.tmpl: Expanded startup protocol with hook-first flow

Each template now includes:
1. Check hook first (gt mol status)
2. If empty, check mail for attached work
3. Self-pin protocol (gt mol attach-from-mail) if needed
4. Role-specific fallback behavior

+Unlike polecats, you're human-managed. But the hook protocol still applies:
+
+```bash
+# Step 1: Check your hook
+gt mol status                    # Shows what's attached to your hook
+
+# Step 2: Hook has work? → RUN IT
+# Hook empty? → Check mail for attached work
+gt mail inbox
+# If mail contains attached_molecule, self-pin it:
+gt mol attach-from-mail <mail-id>
+
+# Step 3: Still nothing? Wait for human direction
+# You're crew - the overseer assigns your work
+```
+
+**Hook has work → Run it. Hook empty → Check mail. Nothing anywhere → Wait for overseer.**
+
+Your pinned molecule persists across sessions. The handoff mail is just context notes.
